Description

  The present invention relates to a mist spraying device for spraying hot water mist (sauna mist) and cleaning liquid mist.

  Conventionally, it is generally known to perform a mist sauna by spraying hot water mist into the bathroom, but it will propagate from organic pollutants such as mold and bacteria in the bathroom or body dirt. It did not suppress the slime caused by the metabolite of the fungus.

  Therefore, conventionally, a first function unit for ventilating the air in the bathroom, a second function unit for supplying warm air into the bathroom, a third function unit for spraying hot water mist, and the bathroom A multi-functional drying apparatus having a fourth functional unit that sprays a mist of a cleaning liquid is known (for example, see Patent Document 1).

  In the conventional example shown in the above-mentioned Patent Document 1, it is a structure in which either hot water or cleaning liquid is selectively sprayed from a common nozzle. Therefore, when cleaning liquid mist is sprayed during bathroom cleaning by the fourth functional unit. If the water droplet (cleaning liquid) has a small particle size that is likely to float in the bathroom space, the surface area per unit volume of the water droplet is relatively large, and the heat of the water droplet is reduced in the bathroom air before falling. Will be taken away by. Therefore, the heat of this water droplet is taken away and reaches the object to be cleaned such as a bathroom wall in a low temperature state, compared with the case of spraying a cleaning liquid with a high temperature and a large particle diameter on the object to be cleaned. There is a problem that dirt such as oil stains on an object is difficult to remove.

  Furthermore, when spraying high temperature water mist during the mist sauna operation by the third functional unit, if the water droplet (hot water) has a large particle diameter that is difficult to float in the bathroom space, The surface area of the water becomes relatively small, and the heat of the water droplets is hardly taken away by the bathroom air, so that the air in the bathroom falls to the bathroom floor etc. without being heated, and it is impossible to experience a hot and humid mist sauna There is.

Japanese Patent Laid-Open No. 11-316083

  The present invention has been invented in view of the above-described conventional problems, and is intended to float high-temperature and high-humidity mist during a mist sauna. A mist spraying device that can easily regulate spraying in a direction that you do not want to get wet with the cleaning liquid even when the spraying range of the cleaning liquid is expanded. There is to do.

In order to solve the above-mentioned problems, the present invention comprises a mist sauna nozzle 10 for spraying hot water mist and a bathroom cleaning nozzle 4 for spraying cleaning liquid mist during bathroom cleaning. The nozzle hole diameter and the spray flow rate of each of the nozzles 4 and 10 are set so that the particle diameter is small enough to float in the air and the mist of the cleaning liquid is large enough not to float in the air. In the mist spraying apparatus, the bathroom washing nozzle 4 includes a nozzle tip 60 provided with a swirling flow generating means in the nozzle body 63, and a cylindrical portion 66 is formed on the upstream side of the nozzle tip 60. A nozzle hole 60b communicating with the outlet 65 of the nozzle body 63 is formed on the downstream side of the nozzle tip 60, and tapers from the tube portion 66 toward the nozzle hole 60b. 60c and injection hole 60a are sequentially formed, the hole diameter of the injection hole 60a is set smaller than the inner diameter of the tube portion 66, and the taper portion 60c has an upstream end on the inner peripheral surface of the tube portion 66. The cylinder portion 66 is formed from the upstream end surface to the upstream end portion of the tapered portion 60c . The cylindrical portion 66 is continuous and has a downstream end portion continuous to the inner peripheral surface of the injection hole 60a. The cleaning liquid flowing into the nozzle main body 63 flows into the cylindrical portion 66 through the inflow groove 70 and turns into a swirling flow through the tapered portion 60c. The cleaning liquid that flows into the injection hole 60a while reducing its rotation radius collides with the inner peripheral surface of the injection hole 60a while colliding with the inner peripheral surface of the injection hole 60a, so that water droplets are refined and become water droplets from the injection port 60b. The above is injected Minimum isthmus dimension washing liquid passes in chamber cleaning nozzle 4 is characterized in that there is a more 0.5 mm.

  With such a configuration, at the time of the mist sauna, water droplets having a small particle diameter that can easily float in the bathroom space can be sprayed by the mist sauna nozzle 10, so that the surface area per unit volume of the water droplet (hot water) has a large particle diameter. Since it is larger than the one, the heating of the air in the bathroom 13 is promoted until it falls, and a hot and humid mist sauna can be experienced. On the other hand, at the time of bathroom cleaning, since the mist of the cleaning liquid having a large particle diameter that is difficult to float in the bathroom space can be sprayed from the bathroom cleaning nozzle 4, the surface area per unit volume of the water droplet (cleaning liquid) is smaller than the small particle diameter. Therefore, it becomes possible to reach the object to be cleaned such as bathroom wall with the temperature kept as high as possible, which facilitates heating of the wall surface and easily removes dirt such as oil stain, It becomes possible to suppress. Furthermore, since the cleaning liquid is sprayed in the form of a mist, the cleaning liquid can be used effectively without being wasted compared to the spraying of the cleaning liquid in the form of a shower.

  Further, it is preferable to dispose a scissors 26 for blocking the spraying range of the cleaning liquid at the side position of the bathroom cleaning nozzle 4, and in this case, spraying in a direction in which the scrubbing 26 does not want to be wet with the cleaning liquid is simplified. Can be regulated.

  In addition, the ridge 26 is preferably formed in a substantially annular shape that circulates around the bathroom washing nozzle 4 and is formed with a dividing groove 27 that can be divided into a predetermined length in the circumferential direction. Since the circumferential length of the gutter 26 can be made variable, the spray blocking range Z can be easily changed in accordance with the size of the object that is not desired to be wetted.

  Also, a fixing projection 29a is provided on either one of the upper end portion of the tub 26 and the tub mounting portion 36 around the bathroom washing nozzle 4 facing the tub 26, and the fixing projection 29a is inserted on either side. It is preferable to provide an insertion hole 29b for fixing, and in this case, since the rod 26 can be fixed at an arbitrary angle around the bathroom washing nozzle 4, the direction of the rod 26 is adjusted in accordance with the direction of the object that is not desired to be wetted. Can be easily changed.

  In addition, it is preferable that the cleaning liquid is made of electrolyzed water containing hypochlorous acid, and an electrolyzed water recovery container for recovering electrolyzed water dripped from the coffin 26 is disposed at a position below the coffin 26. The electrolyzed water containing hypochlorous acid stored in the electrolyzed water recovery container can be effectively used for sterilization in places other than the bathroom, for example, around the water in the kitchen.

  The present invention provides a mist spraying apparatus that can enhance a cleaning effect by mist of a cleaning liquid during bathroom cleaning, while allowing a high temperature and high humidity mist sauna to be experienced during the mist sauna.

  Moreover, even when the spraying range of the cleaning liquid is widened, the present invention can easily regulate spraying in a direction in which the cleaning liquid is not desired to be wetted by using the soot.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 1 is a piping example of a bathroom heater / dryer provided with the mist spraying device of the present invention, FIG. 2 is a configuration diagram of the bathroom heater / dryer, and FIG. 3 is an explanatory diagram of an installation example of the bathroom heater / dryer. .

  The bathroom cleaning apparatus 1 according to the present embodiment has a function as a mist sauna, a function as a bathroom heating / ventilation apparatus, and a bathroom cleaning function using electrolytic water containing hypochlorous acid, and is installed on the ceiling of the bathroom 13. The 3 is a remote control operation unit installed outside the bathroom 13, and switches such as a mist sauna operation switch, a bathroom washing switch, a heating operation switch, a ventilation operation switch, a drying operation switch, and a cool air operation switch (see FIG. 3). Not shown).

  As shown in FIG. 1, the bathroom cleaning apparatus 1 includes a heater body 2 that supplies hot air into the bathroom 13, an electrolyzed water generator 6 that generates electrolyzed water containing hypochlorous acid when energized, and a mist sauna. The mist spraying device 3 including the nozzle 10 for the bathroom and the nozzle 4 for washing the bathroom, the ventilation fan 42 that sucks the air in the bathroom 13 and discharges it to the outside, and the control unit 39 (FIG. 11) for controlling these are mainly used. It is configured.

  The control unit 39 receives each detection signal from the bathroom temperature sensor 9, the hot water going-out temperature sensor 17, the mist temperature sensor 18, and the hot water return temperature sensor 21 in addition to the remote control signal commanded from the remote control operation unit 15. Based on the detection result, it is constituted by a microcomputer that drives and controls each component such as the heater body 2, the electromagnetic valves 22 and 23 of the mist spraying device 3, the electrolyzed water generating device 6, and the ventilation fan 42.

  As shown in FIG. 2, the ventilation fan 42 is provided in the ventilation duct 41, and prevents backflow of air from the outside due to reverse wind pressure or the like between the ventilation fan 42 and the ventilation outlet of the ventilation duct 41. A backflow prevention shutter 24 is provided. The backflow prevention shutter 24 is opened by swinging around a fulcrum by the wind pressure due to ventilation during ventilation, and when the ventilation is stopped, the ventilation duct 41 is blocked by its own weight and prevents outside air from entering the bathroom 13. When the fan motor 35 is operated during ventilation, the air in the bathroom 13 is discharged by the ventilation fan 42 to the outdoor space outside the bathroom 13 through the ventilation duct 41 and the vent cap 40.

  In the apparatus casing 25 of the bathroom cleaning apparatus 1, as shown in FIG. 1, the circulation fan 5 and the air that is ventilated by the circulation fan 5 are heated by the hot water supplied from the heat source unit 14 (FIG. 3). A heat exchanger 7 for heat and a heat valve 8 for adjusting the amount of hot water supplied to the heat exchanger 7 for heating are accommodated. The heating heat exchanger 7 is disposed in the middle of the heating hot water conduit 16 through which the hot water from the heat source unit 14 circulates, and the heat from the circulation fan 5 is exchanged for heating by opening the thermal valve 8. It is heated by the vessel 7 and is supplied into the bathroom 13 from a movable louver 30 (FIG. 2) provided at the lower hot air outlet 31. Further, in the middle of the heating hot water pipe 16, mist heating hot water for heating the mist heat exchanger 11 composed of a liquid heat exchanger housed in a mist box 32 installed on the equipment casing 25. A pipe line 19 is branched and connected. The upstream end of the mist heating hot water pipeline 19 is branched and connected to the upstream position of the heating valve 8 of the heating hot water pipeline 16, and the downstream end of the mist heating hot water pipeline 19 is the heating of the heating hot water pipeline 16. The heat exchanger 7 joins the downstream position.

  Furthermore, a bathroom cleaning / mist water supply pipe 20 is provided from the mist box 32 to the equipment casing 25, and the mist heat exchanger 11 is disposed in the middle of the pipe. The upstream side of the mist heat exchanger 11 of the bathroom cleaning / mist water supply pipe 20 is connected to an external water pipe via an electrolyzed water generator 6 described later. The portion downstream of the heat exchanger 11 for mist in the water supply conduit 20 for washing and mist for bathrooms branches in two directions, namely, a solenoid valve for mist sauna 22 and a solenoid valve for bathroom washing 23. A mist sauna nozzle 10 is connected to the downstream side, and a bathroom cleaning nozzle 4 is connected to the downstream side of the bathroom cleaning electromagnetic valve 23. The bathroom washing nozzle 4 and the mist sauna nozzle 10 are respectively arranged facing the inside of the bathroom 13 from the opening hole on the lower surface of the equipment casing 25. In this example, when the electromagnetic valve 22 for mist sauna is opened, water droplets having a particle size of about 50 to 100 μm can be sprayed to enjoy the mist sauna, and when the electromagnetic valve 23 for bathroom cleaning is opened, the nozzle for bathroom cleaning is opened. Water droplets having a particle size of about 100 to 300 μm are sprayed from 4 and are used for bathroom cleaning.

  When the water temperature supplied from the mist heating hot water pipe 19 to the mist heat exchanger 11 becomes appropriate in the middle of the mist heating hot water pipe 19 branched from the heating hot water pipe 16. A water proportional valve 12 for adjusting the flow rate of the hot water supplied to the mist heat exchanger 11 and a hot water return temperature sensor 21 for detecting the return temperature of the circulating hot water from the mist heat exchanger 11 are respectively provided. is set up. It is possible to shut off the hot water supplied to the mist heat exchanger 11 by fully closing the water proportional valve 12. Further, a mist temperature sensor 18 for detecting the temperature of water discharged from the mist heat exchanger 11 is installed.

The electrolyzed water generating device 6 includes an electrolyzer that generates electrolyzed water containing hypochlorous acid by passing an electric current between electrodes immersed in the electrolyzed water, and by supplying a direct current to the electrolyzer. In the positive electrode, chlorine ions (2Cl ⁻ ) contained in the supplied tap water are deprived of electrons (2e ⁻ ) by an oxidation reaction to generate chlorine (Cl ₂ ), and in the liquid, generated chlorine (Cl ₂ ) reacts with water (H ₂ O) to produce hypochlorous acid (HOCl) having a bactericidal action. In the negative electrode, hydrogen ions (2H ⁺ ) and electrons (2e ⁻ ) are combined by a reduction reaction to generate hydrogen gas (H ₂ ).

  Next, an example of the mist sauna operation start operation will be described. When the mist sauna operation switch of the remote control operation unit 15 is pressed, a signal for instructing the controller 39 (FIG. 11) to start the mist sauna operation is sent, and an operation signal is sent to the heat source unit 14 (FIG. 3) for supplying hot water. The machine 14 starts the heating operation. Next, the hot air-side thermal valve 8 and the mist-side water proportional valve 12 are opened, and the circulating hot water at 80 ° C. starts to circulate in the heating hot water pipe 16 and the mist heating hot water pipe 19. Next, when the temperature of the warm water reaches 60 ° C. or higher, the circulation fan 5 is turned on and warm air is sent to the bathroom 13. Thereafter, when the bathroom temperature becomes 25 ° C. or higher, the mist sauna electromagnetic valve 22 is opened, and mist spraying of hot water is started from the mist sauna nozzle 10.

  Next, an example of the bathroom cleaning operation will be described. Hereinafter, warm water or electrolyzed water used for cleaning is generically defined as a cleaning solution.

  First, bathroom cleaning with warm water will be described. When the bathroom cleaning switch of the remote control operation unit 15 is pressed, a signal for instructing the control unit 39 to start the bathroom cleaning operation is sent, and an operation signal is issued to the heat source unit 14 (FIG. 3) for supplying hot water, and the heat source unit 14 is heated. Start driving. Next, the water proportional valve 12 on the mist side is opened, and the circulating hot water at 80 ° C. starts to circulate in the mist heating hot water pipe 19, and the hot water is supplied to the mist heat exchanger 11. Thereafter, the bathroom cleaning electromagnetic valve 23 is opened, and mist spraying of warm water (cleaning liquid) is started from the bathroom cleaning nozzle 4. By spraying warm water in this way, soap residue, sebum and the like can be washed away effectively.

  In washing with warm water, the temperature rises and microorganisms such as molds and germs are likely to propagate. Therefore, in order to lower the temperature of an object to be cleaned such as a bathroom wall after washing, the water proportional valve 12 on the mist side is fully closed, and the inflow of the circulating hot water from the heat source unit 14 to the hot water pipe 19 for heating the mist is performed. By stopping, the heating of the mist heat exchanger 11 is stopped, and the temperature of the cleaning liquid sprayed from the bathroom cleaning nozzle 4 can be lowered to about the supplied water temperature (normal temperature).

  On the other hand, in order to further enhance the cleaning effect, during the bathroom cleaning operation, the electrolyzed water generating device 6 is energized to generate hypochlorous acid according to a command from the control unit 39, and electrolysis containing hypochlorous acid is included. Water is sprayed from the bathroom washing nozzle 4. Thereby, compared with the case of warm water, the to-be-cleaned object can be sterilized more effectively by the sterilization effect of hypochlorous acid.

  Here, in the present invention, the particle diameter of the water droplets of the sauna mist sprayed from the mist sauna nozzle 10 is about 50 to 100 μm, and the nozzles of the mist sauna nozzle 10 occupy most of them are 100 μm or less. The hole diameter and the spray flow rate are set. Specifically, the nozzle diameter of the mist sauna nozzle 10 is set to about 0.7 mm, and the spray flow rate is set to 0.25 to 0.5 liter / min. This makes it easy for the water droplets of the sauna mist to float in the bathroom space, and heats the air in the bathroom 13 by heat exchange between the water droplets (warm water) and the air in the bathroom 13 before falling on the bathroom floor. Will be promoted. Therefore, it becomes possible to experience a hot and humid mist sauna.

  On the other hand, the particle size of the water droplets (hot water or electrolyzed water containing hypochlorous acid) of the cleaning solution sprayed from the bathroom cleaning nozzle 4 is set to about 100 to 300 μm, which is difficult to float in the air, and the average value of the particle sizes Is set to about 150 μm, the nozzle hole diameter and the spray flow rate of the bathroom washing nozzle 4 are set. This will be specifically described below.

  For example, there are various specific configurations for spraying a mist having an average particle diameter of about 150 μm. In this embodiment, a nozzle tip provided with a swirl flow generating means in the nozzle body 63 of the bathroom washing nozzle 4. 60 is configured to generate a swirling spray from the nozzle hole 60a of the nozzle tip 60. More specifically, as shown in FIG. 12, the bathroom cleaning nozzle 4 includes a cylindrical nozzle body 63 and a ceramic nozzle tip 60 fixed inside the nozzle body 63. In the present embodiment, the nozzle body 63 is formed by plating copper. As shown in FIGS. 13A and 13B, the ceramic nozzle tip 60 has a substantially cylindrical shape, and a cylindrical portion 66 having an inflow groove 70 is formed on the upstream end surface of the nozzle tip 60. An injection hole 60b communicating with the outlet 65 of the nozzle body 63 is formed at the center of the downstream end face, and a tapered part 60c and an injection hole 60a are sequentially formed from the cylindrical part 66 toward the injection hole 60b. The hole diameter of the injection hole 60a is set to be smaller than the inner diameter of the cylindrical portion 66, and the tapered portion 60c has an upstream end continuous with the inner peripheral surface of the cylindrical portion 66 and a downstream end at the inner peripheral surface of the injection hole 60a. It is formed in the shape of a conical surface that is continuous with.

  The front end open end of the cylindrical portion 66 is closed by a closer 61 urged by a spring 62 provided inside the nozzle body 63. A pair of inflow grooves 70 are notched at two locations in the circumferential direction of the cylindrical portion 66. Each inflow groove 70 is formed from an inflow groove inlet 70 a on the outer periphery of the cylinder portion 66 toward an inflow groove outlet 70 b of the inner wall 60 d of the cylinder portion 66, and the cleaning liquid W flowing into the nozzle body 63 passes through the inflow groove 70. It flows into the nozzle tip 60 via.

  In this embodiment, the center line of the inflow groove 70 connecting the inflow groove inlet 70a and the inflow groove outlet 70b is not the center line E (FIGS. 13B and 14A) passing through the injection hole 60a, but a cylinder An inflow groove 70 is formed by being deflected toward the inner wall 60d side of the portion 66. That is, since the center line of the inflow groove 70 is inclined so as to be substantially parallel to the inner wall 60d of the cylindrical portion 66, the inflow groove 70 flows in from the inflow groove inlet 70a and is introduced into the nozzle tip 60 through the inflow groove outlet 70b. The flow of the cleaning liquid W is introduced into the nozzle tip 60 as a swirling flow indicated by an arrow in FIG. The diameter of the injection hole 60a is about 0.5 to 1 mm, and the groove width of the inflow groove 70 is about 0.5 to 1 mm. Thereby, since the minimum narrow part dimension (groove width of the inflow groove 70 in this embodiment) through which the cleaning liquid W passes in the bathroom cleaning nozzle 4 can be about 0.5 to 1 mm, the electrolyzed water generating device 6 Even when deposits are generated in the electrode, the deposits can easily pass through the nozzle 4 for washing the bathroom, and clogging in the nozzle 4 for washing the bathroom can be prevented.

  On the other hand, when spraying water droplets with an average particle diameter of about 150 μm by a spray method in which a microhole is provided in the shower head, the hole diameter of the microhole is reduced to about the particle diameter of the sprayed water droplet. Therefore, there is a possibility that the precipitate is likely to be clogged as compared with the present embodiment.

  That is, in this embodiment, since the swirling flow type bathroom washing nozzle 4 is employed as described above, even when precipitates are generated in the electrode of the electrolyzed water generating device 6, the deposits are not easily clogged. It has become.

  The flow rate of the cleaning liquid W supplied to the bathroom cleaning nozzle 4 is set to 0.5 to 2 liters / minute, and the cleaning liquid W flowing into the nozzle body 63 flows into the cylindrical portion 66 of the nozzle tip 60. 14 passes through the groove 70 and flows into the injection hole 60a via a tapered portion 60c formed from the inner surface of the cylindrical portion 66 to the inner peripheral surface of the injection hole 60a as a swirling flow indicated by an arrow in FIG. The swirling flow W flows into the injection hole 60a through the taper portion 60c while reducing the rotation radius. Since this inflowing cleaning liquid W collides with the inner peripheral surface of the injection hole 60a while swirling, the water droplets are made finer and injected from the injection port 60b as water droplets having an average particle size of about 150 μm at about 100 to 300 μm. Is.

  As a result, the water droplets of the cleaning liquid are less likely to float in the air of the bathroom 13 and reach the object to be cleaned such as the bathroom wall while maintaining the temperature of the water droplets as much as possible, and the heating of the wall surface is promoted. Dirt such as oil stains can be easily removed, and slimming and dirt can be sufficiently suppressed.

  Furthermore, since the cleaning liquid is sprayed in the form of a mist, the cleaning liquid can be used effectively without being wasted compared to the spraying of the cleaning liquid in the form of a shower. For example, when the cleaning liquid has an average particle diameter of 150 μm and is sprayed in a mist shape, the volume of one particle of the cleaning liquid is about 300% compared to the case where the average particle diameter of the cleaning liquid is about 1 mm and sprayed in a shower shape. Therefore, the consumption of the cleaning liquid when the same number of cleaning liquid particles are sprayed can be reduced to about one-third, and in this embodiment, the cleaning liquid is not sprayed in the form of a shower without spraying the particles. Since the spray is sprayed in the form of a mist of a fraction of a 1 mm diameter, the cleaning liquid can be sprayed over a wide range with a small consumption of the cleaning liquid, and the cleaning liquid is scattered in addition to the object to be cleaned. Even in this case, the amount of wasteful consumption of the cleaning liquid is small and resource saving. In addition, since the consumption of the cleaning liquid is small, the treatment capacity of the electrolyzed water generating device 6 and the mist heat exchanger 11 may be small, and the bathroom cleaning device can be downsized.

  By the way, at the time of bathroom cleaning, it is preferable that the spray range of the cleaning liquid from the bathroom cleaning nozzle 4 is as wide as possible. Hereinafter, an embodiment for expanding the spray range of the cleaning liquid will be described, and then an embodiment for blocking the spray liquid spray range will be described.

  First, an example of expanding the spray range of the cleaning liquid from the bathroom cleaning nozzle 4 will be described.

  Incidentally, the spray spread angle θ1 of the hot water sprayed from the mist sauna nozzle 10 during the mist sauna operation is effective toward the place where the bather is present in the bathroom 13, as shown in FIG. 4 (a). It is set to about 60 to 80 ° so that the mist for sauna is sprayed. As a result, almost no mist for the sauna can hit the bathroom wall.

  On the other hand, in the bathroom cleaning operation, the spray spread angle θ2 of the cleaning liquid sprayed from the bathroom cleaning nozzle 4 has a wide range toward the object to be cleaned in the bathroom 13 as shown in FIG. It is set to about 100 to 180 ° so that the cleaning liquid is sprayed. Accordingly, the cleaning liquid can be applied to almost the entire area of the bathroom wall, and the cleaning of the bathroom 13 is promoted.

  Further, when installing the bathroom cleaning device 1 on the ceiling of the bathroom 13, the bathroom cleaning nozzle 4 is not necessarily located near the center of the bathroom 13 in a plan view. In many cases, it is not located near the center of the ceiling, but at a position close to the bathtub side wall surface 13a (a position away from the washing wall side wall surface 13b). In this case, as shown in FIG. 5 (a), when the central direction of the spray of the cleaning liquid is directly below (the angle between the central direction of the spray of the cleaning liquid and the vertical line A is 0 °), Although the cleaning liquid reaches the area close to the ceiling, the cleaning liquid hardly reaches the area close to the ceiling with respect to the washing wall side wall surface 13b. For this reason, the difference B in the spray height of the cleaning liquid on the washing wall side wall surface 13b with respect to the bathtub side wall surface 13a becomes large, and the washing height of the washing wall side wall surface 13b becomes insufficient.

  In order to improve this, as shown in FIG. 5 (b), the center direction D of the bathroom washing nozzle 4 is deflected at an angle α of 10 ° to 20 ° from the vertical line A toward the washing field side wall surface 13b. It is preferable to attach it. Accordingly, since the distance from the bathroom cleaning nozzle 4 to the washing place side wall surface 13b is larger than the distance from the bathroom cleaning nozzle 4 to the bathtub side wall surface 13a, the cleaning liquid is sprayed onto the bathtub side wall surface 13a. Although the upper limit of the range is somewhat lowered, the upper limit of the spray range of the cleaning liquid is increased with respect to the washing place side wall surface 13b. As a result, the height difference C is smaller than the difference B (FIG. 5A) when the central direction of the spray of the cleaning liquid is directly below. As a result, the bathroom wall is not increased without increasing the spray spread angle θ2. The spraying range of the cleaning liquid can be expanded over almost the entire area.

  In many cases, the bathtub 50 is installed adjacent to one of the wall surfaces of the bathroom 13 and the bathroom cleaning apparatus 1 having a function as a mist sauna is installed almost directly above the bathtub 50. In this case, as shown in FIG. 6A, when the bathroom cleaning nozzle 4 is in the vicinity of the center in a side view of the bathroom cleaning device 1, the cleaning liquid sprayed from the bathroom cleaning nozzle 4 is the edge 50 a of the bathtub 50. As a result, a region X that becomes a blind spot of the spray is generated in the apron peripheral portion of the bathtub 50 on the washing place 51 side, and since this region X is wide, the range in which the cleaning liquid reaches is narrowed.

  Therefore, as shown in FIG. 6B, the bathroom cleaning nozzle 4 is disposed near the end of the bathroom cleaning device 1 so that the bathroom cleaning device 1 is not changed without changing the mounting position of the bathroom cleaning device 1. Only the nozzle 4 for use can be positioned on the center side of the bathroom 13, whereby the area Y in which the sprayed cleaning liquid is difficult to be applied can be made smaller than the area X in FIG. . Further, since the cleaning liquid can easily reach the narrow area Y by the cleaning by the splash, the range in which the cleaning liquid reaches can be expanded.

  As described above, the spraying range of the cleaning liquid can be expanded by changing the design of the mounting angle and the mounting position of the bathroom cleaning nozzle 4 with respect to the bathroom cleaning apparatus 1.

  Next, an example of blocking the spray range of the cleaning liquid will be described.

  As shown in FIG. 8A, when there is a portion where the cleaning liquid is not sprayed on a part of the bathroom wall, such as a bay window 52, the cleaning liquid spray range is extended over almost the entire area of the bathroom wall. Has a disadvantage in that the cleaning liquid is sprayed on the exit window 52 to wet the exit window 52.

  Therefore, in the present invention, as shown in FIG. 8B, a gutter 26 for restricting the spray range to the bay window 52 is attached in the vicinity of the bathroom washing nozzle 4.

  FIG. 7A shows an example of the flange 26, and FIGS. 7B to 7D show an example of the attachment state of the flange 26. FIG.

  As shown in FIG. 7A, the ridge 26 of this example is formed in a substantially annular shape that circulates around the bathroom washing nozzle 4 and has a plurality of dividing grooves 27 that can be divided into a predetermined length in the circumferential direction. I have. Specifically, the flange 26 has a substantially semi-cylindrical surface shape obtained by curving a resin-made rectangular piece in an arc shape, and a V-groove-shaped dividing groove 27 is circumferentially parallel to the axial direction of the inner surface. A plurality of ridges 26 are formed at intervals of the dividing grooves 27 using a tool such as a knife or a ridge. By dividing the flange 26 at the position of the dividing groove 27, the length of the flange 26 in the circumferential direction can be changed as appropriate.

  Further, as shown in FIGS. 7B to 7D, a fixing projection 29 a is provided on the upper end of the rod 26 in the axial direction so as to wash the bathroom on the lower surface of the equipment casing 25 of the bathroom washing apparatus 1. An annular fixing guide groove 28 centering on the bathroom cleaning nozzle 4 is formed in the ridge mounting portion 36 around the nozzle 4, and the fixing protrusion 29 a is inserted into the bottom surface of the fixing guide groove 28. A plurality of fixing insertion holes 29b are provided at intervals in the circumferential direction. A structure in which the fixing insertion hole 29b is provided on the upper end surface side of the flange 26 and the fixing protrusion 29a protrudes from the fixing guide groove 28 is also possible.

  In order to attach the flange 26 to the side position of the bathroom cleaning nozzle 4, either the fixing protrusion 29a is inserted while the upper end surface of the flange 26 provided with the fixing protrusion 29a is inserted into the fixing guide groove 28. The flange 26 is fixed by being inserted into one fixing insertion hole 29b. In the fixing protrusion 29a of this example, the fixing protrusion 29a is held in the fixing insertion hole 29b by a repulsive force caused by deformation in a state where the fixing protrusion 29a is inserted into the fixing insertion hole 29b. Since the spring 26 is configured to have a spring property, the trough 26 once attached to the fixing insertion hole 29b is inadvertently in the equipment casing 25 of the bathroom cleaning device 1 due to vibration or its own weight due to the operation of the bathroom cleaning device 1. It does not come off the heel attachment portion 36.

  Specific examples of the use of the bag 26 are shown in FIGS. An arc-shaped barrier is formed on the circumference centering on the bathroom cleaning nozzle 4 by the rod 26, and in the direction where the rod 26 is present by blocking the cleaning liquid sprayed from the bathroom cleaning nozzle 4. The cleaning liquid will not scatter. Further, when the circumferential length of the rod 26 is increased, the horizontal spray blocking range Z can be expanded as shown in FIG. 9A, and conversely, when it is shortened, the length is shown in FIG. 9B. As described above, since the horizontal spray blocking range Z can be narrowed, the spray blocking range Z can be easily changed according to the width dimension of the bay window 52.

  Further, as shown in FIG. 7B, a fixing insertion hole 29b for inserting the fixing protrusion 29a is appropriately selected from among a plurality of fixing insertion holes 29b provided on the bottom surface of the fixing guide groove 28. By doing so, as shown in FIG. 9 (c) or (d), it becomes possible to change the mounting direction of the tub 26 with respect to the bathroom washing nozzle 4, and the spray blocking range Z can be arbitrarily changed according to the mounting position of the bay window 52. It becomes a possible structure.

  Therefore, even if the installation conditions are such that the cleaning liquid is sprayed and the exit window 52 gets wet, the spray area of the cleaning liquid from the bathroom cleaning nozzle 4 is not narrowed to the exit window 52 side. There is an advantage that the cleaning liquid sprayed in the direction can be blocked by the eaves 26 and the exit window 52 is prevented from getting wet by the cleaning liquid.

  FIG. 10 shows another embodiment of the heel 26. Instead of providing the fixing guide groove 28 (FIG. 7), the spray blocking rod 26 of the present example is substantially C in plan view for holding the bathroom washing nozzle 4 detachably as shown in FIG. 10 (a). A letter-shaped nozzle clamp 37 is integrally provided at the upper end of the collar 26. Other configurations are the same as those in FIG. In this example, as shown in FIG. 10 (b), the annular clamp groove 38 provided on the outer peripheral surface of the bathroom cleaning nozzle 4 by the nozzle clamp 37 when the fixing projection 29a is inserted into the fixing insertion hole 29b. By fitting over more than half a circumference, the collar 26 is held at the outer circumferential position centering on the bathroom washing nozzle 4. In addition, the fixing protrusion 29a of this example does not have a spring property, and the nozzle clamp 37 has a spring property, and the nozzle clamp 37 can grip the bathroom washing nozzle 4 from an arbitrary angle. The attachment position of 26 can be changed freely. Also in this example, by appropriately selecting any one of the fixing insertion holes 29b for inserting the fixing protrusion 29a from among the plurality of fixing insertion holes 29b, the direction of the spray blocking range can be changed. Becomes easy.

  As yet another embodiment, an electrolyzed water recovery container (not shown) for recovering electrolyzed water containing hypochlorous acid dripping from the coffin 26 is provided at a position below the coffin 26 (FIGS. 9 and 10). It is desirable to arrange. As a result, the cleaning liquid containing hypochlorous acid dripped from the wall 26 to the bathroom 13 floor at the time of bathroom cleaning can be recovered in the electrolytic water recovery container, and the recovered cleaning liquid can be removed by making the electrolytic water recovery container removable. Can be used for sterilization other than the bathroom 13. Further, it is more preferable that the electrolytic water recovery container be sealed with a lid, so that chlorine released from the recovered cleaning liquid is not diffused into the air and the sterilizing power can be maintained even after the time has elapsed after recovery.
